Answer:
c. 3 / 13
d. 2 / 13
Step-by-step explanation:
c.
A deck of cards has 52 cards. There are cards of 4 suits- Spades, Hearts, Diamonds and Clubs.
So, there are 52/4= 13 cards of each suit.
Among these 13 cards, there are 3 picture cards or face cards as they are called. These are the Jack, Queen and King cards.
So, the number of total picture cards = 4*3 = 12
the number of cards are 52
theoretical probability formula: P = favorable events/ possible events
P = 12 / 52
P = 3 / 13
d.
there are four aces and four sevens in the deck
so favorable events = 4 + 4 = 8
possible eventas = 52
P = 8 / 52
P = 2 / 13
I think it's different by
Group 2 has a 1 yet group 2 didn't sorry if wrong
-12d+1 is the answer I think. If not then I apologize.....
5 - 8x < 2x + 3
5 - 8x < 2x + 3
<u>-3 - 3 </u> Step 1.
2 - 8x < 2x
<u> +8x +8x </u> Step 2. Missing step
2 < 10x
<u>÷10 ÷10</u> Step 3.
<u>2/10 < x</u>
<u>1/5 < x
The missing step is add 8x to both sides of the inequality.</u>
So you need to mutpies it and then never forget that 0.23
